I like this design as well, but I think having the I/O on top looks better and is a little bit better functionally as it allows easier access when the case is placed lower on the ground (it is a small case so the top is always accessible), plus with a few 90 degree adapters it can very easily turn into a vertical case.
I think I understand why you went with bottom I/O - it is easy to rotate the case and keep the stand?
That is only my opinion of course
but really love the fact that you guys are listening to the feedback! This case is literally turning into my dream case and following it’s design and engineering phase is very exciting!
Also one thing, you said that the only difference to a box are the grooves and the stand, and while I prefer these new case feet, I think that adding a second colour tone would give it a great character - something like the Q58, something subtle though, darker/lighter white/black colour.
